Detector unit with multiple integrated sensing systems and visually pleasing housing
According to one embodiment, a multi-sensing hazard detector for detecting potential dangers may include a back plate and a front casing that is coupled with the back plate to define a housing. A circuit board and a plurality of components may be positioned within the housing. The circuit board may be communicatively coupled with the components. The components may include, among other components, an alarm device, an occupancy sensor, and a smoke chamber. The alarm device may be activatable upon the detection of a potential hazard to warn an occupant of a potential danger, the occupancy sensor may be configured to detect the presence and/or movement of objects external to the hazard detector, and the smoke chamber may be configured to detect the presence of smoke to cause a triggering of the alarm device. The housing may comprise a volume of less than 1024 cubic centimeters.
